According to bspec, result_lines > 31 is only a maximum for latency level 1 through 7. For level 0 the number of lines is ignored, so always write 0 there to prevent overflowing the 5 bits value. This is required to make NV12 work. Changes since v1: - Rebase on top of GEN11 wm changes. It seems to use res_lines for level 0 limit calculations, but still doesn't appear to program it.

When a request is preempted, it is unsubmitted from the HW queue and removed from the active list of breadcrumbs. In the process, this however triggers the signaler and it may see the clear rbtree with the old, and still valid, seqno, or it may match the cleared seqno with the now zero rq->global_seqno. This confuses the signaler into action and signaling the fence. Fixes: d6a2289d ("drm/i915: Remove the preempted request from the execution queue") Signed-off-by:

Commit 99e48bf9 ("drm/i915: Lock out execlist tasklet while peeking inside for busy-stats") added a tasklet_disable call in busy stats enabling, but we failed to understand that the PMU enable callback runs as an hard IRQ (IPI). Consequence of this is that the PMU enable callback can interrupt the execlists tasklet, and will then deadlock when it calls intel_engine_stats_enable->tasklet_disable. To fix this, I realized it is possible to move the engine stats enablement and disablement to PMU event init and destroy hooks. This allows for much simpler implementation since those hooks run in normal context (can sleep). v2: Extract engine_event_destroy. (Chris Wilson) Signed-off-by:

This workaround should prevent a bug that can be hit on a context restore. To avoid the issue, we must emit a PIPE_CONTROL with CS stall (0x7a000004 0x00100000 0x00000000 0x00000000) followed by 12DW's of NOOP(0x0) in the indirect context batch buffer, to ensure the engine is idle prior to programming 3DSTATE_SAMPLE_PATTERN. It's also not clear whether we should add those extra dwords because of the workaround itself, or if that's just padding for the WA BB (and next commands could come right after the PIPE_CONTROL). We keep them for now. References: HSD#1939868 v2: More descriptive changelog and comments. v3: Explain that PIPE_CONTROL is actually 6 dwords, and that we advance 10 more dwords because of that.

The command MEDIA_VFE_STATE checks bits at offset +2 dwords. However, it is possible to have MEDIA_VFE_STATE command with length = 0 + LENGTH_BIAS = 2. In that case check_cmd will read bits from the following command, or even past the end of the buffer. If the offset ends up outside of the command length, reject the command.

The find_reg function was assuming that there is always at least one table in reg_tables. It is not always true. In case of VCS or VECS, the reg_tables is NULL and reg_table_count is 0, implying that no register-accessing commands are allowed. However, the command tables include commands such as MI_STORE_REGISTER_MEM. When trying to check such command, the find_reg would dereference NULL pointer. Now it will just return NULL meaning that the register was not found and the command will be rejected.

Deprecate the silly I915_SET_COLORKEY_NONE flag. The obvious way to disable colorkey is to just set flags to 0, which is exactly what the intel ddx has been doing all along. Currently when userspace sets the flags to 0, we end up in a funny state where colorkey is disabled, but various colorkey vs. scaling checks still consider colorkey to be enabled, and thus we don't allow plane scaling to kick in. In case there is some other userspace out there that actually uses this flag (unlikely as this is an i915 specific uapi) we'll keep on accepting it. Signed-off-by:

Since commit 7b6da818 ("drm/i915: Restore the kernel context after a GPU reset on an idle engine") we submit a request following the engine reset. The intent is that we don't submit a request if the engine is busy (as it will restart active by itself) but we only checked to see if there were remaining requests in flight on the hardware and skipped checking to see if there were any ready requests that would be immediately submitted on restart (the same time as our new request would be). Having convinced the engine to appear idle in the previous patch, we can use intel_engine_is_idle() as a better test to only submit a new request if there are no pending requests. As it happens, this is tripping up igt/drv_selftest/live_hangcheck in CI as we overfill the kernel_context ringbuffer trigger an infinite recursion from within the reset.

In preparation for the next patch, we want the engine to appear idle after a reset (if there are no requests in flight). For execlists, this entails clearing the active status on reset, it will be regenerated on restarting the engine after the reset. In the process, note that a couple of other status flags and checks could be moved into the describing function. Signed-off-by:

Avoid injecting hangs in to the i915->kernel_context in case the GPU reset leaves corruption in the context image in its wake (leading to continual failures and system hangs after the selftests are ostensibly complete). Use a sacrificial kernel_context instead. v2: Closing a context is tricky; export a function (for selftests) from i915_gem_context.c to get it right. Signed-off-by:

When injecting rapid resets, we must be careful to at least wait for the previous reset to have taken effect and the engine restarted. If we perform a second reset before that has happened, we will notice that the engine hasn't recovered and declare it lost, wedging the device and failing. In practice, since we wait for each hanging batch to start before injecting the reset, this too-fast-reset condition can only be triggered when moving onto the next engine in the test, so we need only wait for the existing reset to complete before switching engines. v2: Wrap up the wait inside a safety net to bail out in case of angry hw.

If we remember to cancel the signaler on a request when retiring it (after we know that the request has been signaled), we do not need to carry an additional request in the signaler itself. This prevents an issue whereby the signaler threads may be delayed and hold on to thousands of request references, causing severe memory fragmentation and premature oom (most noticeable on 32b snb due to the limited GFP_KERNEL and frequent use of inter-engine fences). v2: Rename first_signal(), document reads outside of locks.

Chris Wilson authored
Since unbannable contexts are special and supposed not to be causing GPU hangs in the first place, make it clear when they are implicated in said hang. In practice, most unbannable contexts are those created by igt for the express purpose of throwing untold thousands of hangs at the GPU and wish to keep doing so to finish the test. Normally they are cleaned up, but it's when they or the other unbannable kernel contexts stay stuck in an erroneous state that we need to worry and so need highlighting. Suggested-by:

As we ourselves cancel interrupts during reset by clearing the GTIIR, it is possible for the master IIR to indicate a pending IRQ for which we have already cleared from the GTIIR. In this case, the DRM_ERROR are intended and should not be flagged as an error. Signed-off-by:

Chris Wilson authored
Be paranoid and flush the GTIIR after clearing the CS interrupt to be sure it has taken before we re-enable the interrupt handler. We still see early interrupts following reset, the tasklet handling the mmio read before it has been written by the CS. This hopefully reduces the frequency to 0...

There is no requirement for doing the PCODE request polling atomically, so do that only for a short time switching to sleeping poll afterwards.

Currently we see sporadic timeouts during CDCLK changing both on BXT and GLK as reported by the Bugzilla: ticket. It's easy to reproduce this by changing the frequency in a tight loop after blanking the display. The upper bound for the completion time is 800us based on my tests, so increase it from the current 500us to 2ms; with that I couldn't trigger the problem either on BXT or GLK. Note that timeouts happened during both the change notification and the voltage level setting PCODE request. (For the latter one BSpec doesn't require us to wait for completion before further HW programming.) This issue is similar to commit 2c7d0602 ("drm/i915/gen9: Fix PCODE polling during CDCLK change notification") but there the PCODE request does complete (as shown by the mbox busy flag), only the reply we get from PCODE indicates a failure. So there we keep resending the request until a success reply, here we just have to increase the timeout for the one PCODE request we send. v2: - s/snb_pcode_request/sandybridge_pcode_write_timeout/ (Ville) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: <stable@vger.kernel.org> # v4.4+ Acked-by: Chris Wilson <chris@chris-wilson.co.uk> (v1) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=103326Reviewed-by:

Commit e2b763ca ("drm/i915: Remove bitmap tracking for used-pdpes") believed that because it did not insert its freshly allocated page directory into the pd tree, it was safe from the shrinker. I failed to heed the lesson learnt from commit dd19674b ("drm/i915: Remove bitmap tracking for used-ptes") that we need to pin all the levels in the tree before hitting the shrinker or else the shrinker may free an upper layer as we proceed to allocate the tree. Thus leaving dangling pointers everywhere and a GPF should we hit direct reclaim at just the wrong moment. CPU: 0 PID: 7374 Comm: chromium Tainted: P O 4.14.13-1-ARCH #1 Hardware name: Apple Inc.

This patch clears a single bit. The bit is 0 by default but expected not to be set. Explicitly clearing the bit in this patch is intended to indicate some thinking has occurred, and that we want this bit cleared and we are not just excepting the default value. We also stop setting GFX_RUN_LIST_ENABLE, which is correct since that bit is gone. v2 (from Paulo): fix indentation. v3: Changed GEN check to >= 11. Corrected author name. v4 (from Paulo): improve commit message (Daniele). Reviewed-by:

We don't have planar pixel format support implemented for ICL yet. ICL require 2 display planes to be allocated for Planar formats unlike previous GEN. So ICL/GEN11 doesn't require to write Y-plane ddb data in NV12_BUF_CFG register and PLANE_NV12_BUF_CFG register is removed in ICL. This patch removes the PLANE_NV12_BUF_CFG write for ICL.
